; PR20354: when generating code for a vector fabs op,
; make sure that we're only turning off the sign bit of each float value.
; No constant pool loads or vector ops are needed for the fabs of a
; bitcasted integer constant; we should just return an integer constant
; that has the sign bits turned off.
;
; So instead of something like this:
;    movabsq (constant pool load of mask for sign bits)
;    vmovq   (move from integer register to vector/fp register)
;    vandps  (mask off sign bits)
;    vmovq   (move vector/fp register back to integer return register)
;
; We should generate:
;    mov     (put constant value in return register)
